Answer:
This is kind of late, but I hope I could help maybe for a later assignment or assesment.
The estimates of y have become increasingly more precise, with some of the earlier ones having a margin of error of more than 0.8
None of the estimates support newton's theory that y=0
Most of the estimate support Einstein, or at least have a margin of error that accounts for einstien.
Answer:
No, I haven't taken the isat.
Step-by-step explanation:
A. Let x = cheese and
y = chocolate
2x + y = 25
x + y = 20
B. Subtract the second equation from the first.
2x + y = 25
-(x + y = 20)
-—————
x = 5
Plug 5 back in to the second equation and solve for y.
x + y = 20
5 + y = 20
Subtract 5 from both sides.
y = 15
5 cheese and 15 chocolate
Used elimination method because coefficients on the y values were both 1 so it was easy to subtract the equations and eliminate the y variable.
The slope is 4 because you go up 4 and over one which created the slope 4/1 which is just 4
Answer:
Modification has not reduced the number of accidents.
Step-by-step explanation:
A B C D E F G H
Before modification 5 7 6 4 8 9 8 10
After modification 3 7 7 0 4 6 8 2
Difference -2 0 1 -4 -4 -3 0 -8
Mean of differences 
Standard deviation of differences = 
Formula of paired t test :
Df = n-1 = 8-1 =7
t critical> t calculated
So, We failed to reject null hypothesis
Hence modification has not reduced the number of accidents.
